java微信申请退款回调的注意点
public String decryptData(String base64Data, String md532Str) throws Exception {
initialize();
BASE64Decoder decoder = new BASE64Decoder();
Cipher cipher = Cipher.getInstance("AES/ECB/PKCS7Padding");
SecretKeySpec sKeySpec = new SecretKeySpec(md532Str.getBytes(), "AES");
cipher.init(Cipher.DECRYPT_MODE, sKeySpec);
return new String(cipher.doFinal(decoder.decodeBuffer(base64Data)),"UTF-8");
}
原因：AES在JDK正常下载的是有限制的解密位数的 解决：去oracle的javaSE下载对应jce解密jar，下载无敌解密jar包，替换jar中相应jar包
